Application filetl April 10, 1909. Serifll No. 489,082.

attavhom i't may concern: Be 1t known that I, THOMAS J. BAR'ro'w, acitizen of the' United States, residing at Manzanola, in the county-ofOte'ro and State of Colorado, have invented certain new and usefulImprovements in Heaters; and I do hereby declare the following to be afull, clear, andexact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame. My invention relates to new and useful improvements in heaters andmore particularly to that class adapted to be used for heating theatmosphere to'prevent; frost from lnlling fruit on fruit trees, etc.,and my obect is to provide a device of this'class adapted to consumevarious grades of crude oil, gas, or any cheap grade ofoil.

A further object is to provide suitable dampers to regulate the draft ofthe heater.

A further object is to provide a suitable 'chimney and removably attachthe same to the body of the heater and a still further object is toprovide a suitable air duct for the heater.

Other objects and advantages will be hereinafter referred to and moreparticularly pointed out in the claims.

In the accompanying drawings forming part of this application, Figure 1is a central, vertical, sectional view through the heater. F 1g. 2 1s asectional view as seenon line 2 2, Fig. 1, and Fig. 3 is a sectionalview as seen on line 33, Fig. 1.

Referring to the drawings in whichsimilar referencemumerals designatecorresponding parts throughout the several views, 1 indicates the bodyor fire pot of my improved heater, which is preferably circular in crosssection and is provided with a base 2 at its thereby permitting air toenter through the ports 4 in the base 2.

l The upper end 5 of the body is provided with an opening 6, aroundwhich extends a collar .7, said collar being adapted to receive andsupport a chimney 8. The upper end portion 5 is also provided with aplurality of vents 9, with which are adapted to cooperate similar vents10 in a movable plate 11, said plate being held in position on the upperend 5 by introducing bolts orthelike 12 through elongated slots 13in theplate 11, v

the upper ends of the bolts12 being provided with nuts 14 adapted tohold the plate in its proper position, the slots 13 permitting the plateto rotate around the collar 7 and entirely close the vents 9 or leavethe same partially open, a thumb piece 15 being attached to the plate 11to readily accomplish this re suit. The chimney 8 is also provided withan opening 16 ata pbint adjacent its lower end, with which opening isadapted to cooperate a sliding damper 17, the object of said damper andopening being to regulate the draft through the chimney.

Extending upwardly from the bottom 3 and to a point adjacent the upperend of the chimney 8, is an air tube 18, the open end of said tubecommunicating with the space below the bottom 3, whereby air may readilypass upwardly through the .tube and commingle' with the products ofcombustion passing through the chimney, the tube serving as an air mixeras well as for spreading the heat and forcing the same outwardly Inoperation, a quantity of oil, or the like, is placed in the body 1, thechimney 8 being removed to give ready access to the body. A quantity ofwaste or other combustible material is then placed on' the top of theoil in the body and ignited, the plate 11 having been moved to close thevents in the top 5. The burning of the waste will heat the oil to suchan extent as to form a gas, whichwill ignite from the burning waste andexude from the collar 7, after which the chimney is placed in '0 9 orentirely closed and the damper 17 operated to admit air through theopening 16, such admission of air reducing the amount of combustion.lower end, said base supporting the bottom 3 i of the body a distanceabove the ground,

A number of the heaters are to be placed in an orchard, whereby thetemperature of the atmosphere may be increased to such an extent as toprevent freezing of the bloom or fruit on the trees and in view of thefact that cheap grades of oil may be used, this result is accomplishedat a minimum expense.

In view of the great simplicity of my improved heating device, the samecan be very cheaply constructed and'placed in operation and it willlikewise be seen that by providing the dampers as shown, the draftrequired to operate the heater, may be readily regulated.

As shown in Fig. 1, a shield 19 is adapted to be attached to the upperend of the chimrounding said opening,

ney 8,-saidshield being preferably arranged at an an le to the axialcenter of the chimney and y providing a clip 20 to engage the edgeofthe'chimney and support the shield thereon, said shield may be shiftedto any point around the chimney, the object of the shield beingto.regulate-the draft through the chimney and prevent air from blowingdownwardly through the chimney.

What I claim is:

1. In a heating device, the combination with a body having a base at itslower end, an opening in its upper end and a collar sursaid upper endalso having vents therein; of a chimney adapted to fit over said collar,means cooperating with the vents in the upper end of the body toregulate the admission of air into the body and an air tube extendingupwardly from the lower end of the body and into said chimney and spacedtherefrom to form an annular channel. 1

2. In a heater, the combination with a body having a base, an opening inits upper end and a collar surrounding said opening,

said upper end also having vents therein; of a plate having ventsadapted to cooperate with the vents in the upper end portion, said platehavin slots therein, means extending through sai slots to hold the platein position, a chimney adapted to engagethe collar, a damper in saidchimney extending upwardly from the body and partway through saidchimney said air tube being of less diameter than the chimney 'to,forman annular space between the tube and chimney.

- In testimony whereof I have signed my name to this specification inthe presence of witnesses. v
